Yes you can post listings from different areas into OneKey and they will still show up on public sites like Zillow/Realtor/etc.

You can find guidelines for determining material participation, the rules for determining who's a real estate professional and what's active participation, and the special rules that apply to the income and losses from a passive activity held through a publicly traded partnership (PTP) in Publication 925,"Basically, rental is generally passive unless you are a real estate professional, HOWEVER, refer to pub 925 for special rules.  

What wholesaling under current law bans is marketing to the public.

Public Record bedroom number is different than the advertised bedroom number.For instance, Public record and tax assessor says 4, while advertised bedroom number on MLS/listing is 5.The listing agent insists that the bedroom number is correct and that assessor and public information are wrong.What steps do I need to ensure that the advertised bedroom number is correct?

On this forum I doubt anyone will be offended, but if you go to the general public you might want to rethink letting the prospective buyers know that you are ready to insult them for being Looky Lous or doing some "funny business." 

To provide an example, I was previously employed in the legal department of HHM, which at the time was a an affiliate management company of a publicly traded hotel development/operation company where we managed  the portfolio of  hotels as well as provided 3rd party management services.

Quote from @Elias Ramirez: Your county has public records with the name and mailing address of the owner.

I had to learn to navigate public transportation which was non existent where I grew up.

I have seen him get angry at other students in his program who got publicly vocal inside his FB group about the terrible deals in the marketplace.

From an outside viewer, I would be nervous to work with either one of you, since you are fast to go public with any grievance and the realtor has poor communication skills and has no problem blaming external circumstances for lack of a simple courtesy call.
